A 45-year-old woman presented with subarachnoid hemorrhage of World Federation of Neurosurgical Societies grade IV. Cerebral angiography showed a dissecting aneurysm of the right vertebral artery (VA). Internal trapping of the right VA with coils was performed.

MR imaging and 1H-MR spectroscopy in a case of cerebral infarction with transient cerebral arteriopathy.

A case of cerebral infarction with transient cerebral arteriopathy in a 12-year-old female is described. The child showed with an acute onset of left hemiplegia, central facial palsy and aphasia. She was diagnosed with right internal carotid artery obstruction with no predisposing factors for cerebral infarction.

Prognostic factors and therapeutic problems of primary intracranial choriocarcinoma/germ-cell tumors with high levels of HCG.

Objective: Primary intracranial choriocarcinoma (PICCC)/germ-cell tumors (GCTs) with high levels of human chorionic gonadotropin (HCG) (PICCC/GCTs with HL-HCG) are rare and malignant. The goal of this study was to report our 3 cases of PICCC/GCTs with HL-HCG and to review the literature to elucidate the clinical problems and prognostic factors and to discuss the therapeutic modalities of this rare tumor.

Methods: Survival was analyzed in 66 previously reported PICCC/GCTs with HL-HCG including our 3 cases, of which the clinical results have been described in the literature since 1975.

Intracanalicular aneurysm at the meatal loop of the distal anterior inferior cerebellar artery: a case report and review of the literature.

Background: Distal aneurysms of the anterior inferior cerebellar artery (AICA) are rare. Most of the reported cases have been located near the internal auditory meatus. Among these cases, only six located in the internal auditory meatus have been reported in the literature.

Ruptured infectious aneurysm of the distal middle cerebral artery manifesting as intracerebral hemorrhage and acute subdural hematoma--case report.

A 21-year-old woman with severe mitral valve regurgitation due to infectious endocarditis was transferred to our institute in a deep coma with intracerebral hemorrhage and acute subdural hematoma. She had no history of head injury. Brain computed tomography revealed left frontoparietal intracerebral hematoma and adjacent acute subdural hematoma that were evacuated on the day of admission, but the distal middle cerebral artery (MCA) aneurysm remained undetected.
